Here's how to run with the proprietary Nvidia driver on Wayland:

Prerequisites

To use the Plasma Wayland session:

  • Use an up-to-date version of Plasma (explicit sync support was implemented in 6.1)
  • Ensure a reasonably new NVIDIA driver:
    • minimum supported by KWin is 495.44;
    • XWayland apps are usable with 555 and newer.
  • You need to have the Nvidia EGL library installed. It can be a separate package (libnvidia-egl-wayland1) or bundled with the driver package (e.g. nvidia-gl-G06 on openSUSE since 555).
  • To run XWayland apps without flickering, at least XWayland 24.1 is required.

Use the modesetting driver

Check whether the driver is running in modesetting mode:

cat /sys/module/nvidia_drm/parameters/modeset

It should print “Y”. If not, modify your kernel command line and add the line nvidia_drm.modeset=1. Search for “kernel parameters” in your distribution; https://wiki.archlinux.org/index.php/Kernel_parameters is a good starting point.

It is also possible to pass the parameter via module configuration:

echo options nvidia_drm modeset=1 | sudo tee /etc/modprobe.d/nvidia_drm.conf

You need to regenerate the initramfs in case your distribution provides the graphics drivers in initramfs (e.g. sudo update-initramfs -u)
